• As always begin the process by preheating your oven to 350° Fahrenheit and greasing a 9 by 9 baking dish.
• Begin by putting your peanut butter, butter, and sweetener in a mixing bowl , then cream it together using either a stand or a hand mixer.
• Once you have a smooth creamy mixture add the eggs one at a time and mix again until evenly incorporated.
• Next, add the protein powder, salt, baking powder, and vanilla. Mix again on low speed then slowly add the almond flour.
• Once your batter is well mixed add the chocolate chips, and mix on low or by hand until evenly distributed throughout the batter.
• Press the dough out evenly in your prepared baking dish and bake for 15-18 minutes or until the edges have begun to brown and the middle has set.

For The Frosting

• While your bars are baking or cooling mix together your frosting.

  Combine the peanut butter, sweetener, vanilla, and whipping cream in a small mixing bowl. Using a whisk or a fork whip the frosting until all the ingredients have blended together evenly and you have a smooth and creamy frosting.
• Put the frosting in a piping bag, or in a Ziploc bag and snip the corner off. Once your cookie bars are baked and cooled pipe the frosting over the bars in a zig-zag pattern, or pattern of your choice.

  Cut the bars into nine equal pieces, and enjoy!
